Description

Technical Field

[0001] The invention relates to the field of edible fungus liquid strain culture, in particular to an oxygen supply device for edible fungus liquid strain culture. Background Art

[0002] With the development of science and technology, the fermentation technology of liquid edible fungi strains has become increasingly mature. Compared with traditional solid strains, liquid strains have the advantages of easy-to-control fermentation conditions, high activity, less pollution, fast fermentation and low cost. At the same time, edible fungi are aerobic strains and need to maintain sufficient oxygen supply during their cultivation process.

[0003] However, most of the existing oxygen supply devices for culturing liquid spawns of edible fungi cannot supply oxygen to the liquid spawns of edible fungi in the culture tank well. The oxygen introduced into the culture tank will first contact with the liquid spawns of edible fungi in the upper part of the culture tank, while the liquid spawns of edible fungi in the lower part of the culture tank cannot contact with oxygen well due to being stationary for a long time, so that the amount of oxygen absorbed by the liquid spawns of edible fungi in the culture tank is not balanced, which easily leads to uneven fermentation of the liquid spawns of edible fungi, and the oxygen supply effect of the liquid spawns of edible fungi is not good. At the same time, a certain amount of oxygen needs to be introduced into the culture tank at regular intervals during the cultivation process, but oxygen may remain in the trachea after each oxygen is introduced, so that some liquid spawns of edible fungi in the culture tank will be short of oxygen, thereby weakening the respiration of some liquid spawns of edible fungi, resulting in poor fermentation effect of the liquid spawns of edible fungi in the culture tank. Summary of the Invention

[0012] Furthermore, a sealing ring is included, and a sealing ring is provided inside the cover.

[0013] Compared with the prior art, the present invention has the following advantages: first, the lid is opened manually, so that the movable rod, the air bag frame, the oxygen air bag, the connecting hard tube and the air stone are all taken out of the culture tank along with the lid, and then the liquid spawn of edible fungi to be cultured is poured into the culture tank, and then the lid is manually re-attached to the top of the culture tank, and the extrusion block squeezes the hook and drives the two hooks to swing, so that the limit plate moves downward, and then drives the double ball rod to move downward, and the spherical protrusions at the upper and lower ends of the double ball rod will block the upper part and the lower part of the oxygen air bag in turn, so that the oxygen in the oxygen air bag is discharged along the several air ports of the air stone, and at the same time the oxygen gas is discharged. The reduction of oxygen in the bag will cause the air stone to move downward, so that the oxygen discharged by the air stone can fully contact with the liquid edible fungi strain in the culture tank. In this way, the air stone moves upward as the oxygen content in the oxygen bag increases, and moves downward as the oxygen content in the oxygen bag decreases, so that the oxygen stored in the oxygen bag can be passed into the culture tank from top to bottom, thereby more fully supplying oxygen to the liquid edible fungi strain in the culture tank, making the oxygen absorbed by the liquid edible fungi strain in the culture tank more balanced, and then making the fermentation of the liquid edible fungi strain more uniform, making the fermentation of the liquid edible fungi strain more uniform and more complete.

[0014] Secondly, when the moving rod moves up and down, the two stirring plates will stir the liquid edible fungi strain in the culture tank, which can stir the liquid edible fungi strain in the culture tank, so that the oxygen discharged by the air stone can contact the liquid edible fungi strain in the culture tank more fully, thereby allowing the liquid edible fungi strain in the culture tank to ferment more quickly.

[0015] Finally, when the oxygen in the oxygen supply tube enters the oxygen bag, the oxygen bag expands during the upward movement and drives the two extrusion racks to move away from each other. The locking rod will clamp the extrusion rack, so that the extrusion rack will not reset temporarily. When the oxygen bag moves downward to a certain distance, the two extrusion racks will reset and squeeze the residual oxygen in the oxygen bag, so that the edible fungus liquid strain in the culture tank can absorb sufficient oxygen every time, avoiding the phenomenon of insufficient oxygen supply to the edible fungus liquid strain in the culture tank as much as possible, facilitating the development of the edible fungus liquid strain in the culture tank, and making the fermentation of the edible fungus liquid strain better.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1: Oxygen supply device for culturing liquid spawn of edible fungi, such as Figures 1-10As shown, it includes a culture tank 1, a lid 2, a moving rod 3, an oxygen supply tube 4, a floating mechanism, a magnetic switch mechanism and a locking mechanism. The interior of the culture tank 1 is a hollow structure. The lid 2 is clamped on the upper part of the culture tank 1. The moving rod 3 is slidably connected to the upper part of the lid 2. The interior of the moving rod 3 is a hollow structure. The upper part of the moving rod 3 is connected to the oxygen supply tube 4 through a flange. The oxygen supply tube 4 is connected to the interior of the moving rod 3. The floating mechanism for driving the moving rod to float up and down is arranged at the lower part of the moving rod 3. The magnetic switch mechanism is arranged inside the floating mechanism. The locking mechanism is arranged at the lower part of the moving rod 3. The magnetic switch mechanism and the locking mechanism are used to discharge or discharge oxygen in the oxygen supply tube during the upward or downward movement of the floating mechanism.

[0029] The floating mechanism includes an airbag frame 51, an oxygen airbag 52, a connecting hard tube 53 and an air stone 54. The airbag frame 51 is welded to the lower part of the movable rod 3. The oxygen airbag 52 is connected to the inside of the airbag frame 51 through a flange. The upper part of the oxygen airbag 52 is connected to the movable rod 3. The oxygen airbag 52 is used to store oxygen. The lower part of the airbag frame 51 is connected to the connecting hard tube 53 through a flange. The connecting hard tube 53 is connected to the lower part of the oxygen airbag 52. The lower part of the connecting hard tube 53 is connected to the air stone 54 through rivets. The air stone 54 is connected to the lower part of the connecting hard tube 53. Several air ports are opened on the air stone 54, and the air stone 54 is used to discharge oxygen.

[0030] The magnetic switch mechanism includes a magnetic ring 61, a limit plate 62, a magnetic circle 63 and a double ball rod 64. The lower part of the movable rod 3 is slidably connected to the magnetic ring 61. Limit plates 62 are welded on both sides of the magnetic ring 61. The two limit plates 62 are symmetrically arranged. The inside of the movable rod 3 is slidably connected to the magnetic ring 63. The magnetic properties of the magnetic ring 63 are opposite to those of the magnetic ring 61. The magnetic ring 61 and the magnetic circle 63 are attracted to each other. The inside of the magnetic circle 63 is connected to the double ball rod 64 by rivets. The double ball rod 64 is a vertical structure. A spherical protrusion 1 is provided on the upper part of the double ball rod 64, and a spherical protrusion 2 is provided at the lower end of the double ball rod 64. The double ball rod 64 passes through the interior of the movable rod 3, the interior of the oxygen bag 52 and the interior of the connecting hard tube 53.

[0031] When the locking cam 75 is in the closed position, the locking cam 73 is in the closed position, and the two cams 73 are in the closed position, so that the two cams 73 can be locked.

[0032] At first, the oxygen bag 52 is in a deflated state, the bottom of the limit plate 62 contacts the lower part of the reset rod 76, the hook 73 contacts the bottom of the limit plate 62, the two reset springs 72 are compressed, and the spherical protrusion 2 at the lower part of the double ball rod 64 contacts the upper inner part of the connecting hard tube 53 and the lower inner part of the oxygen bag 52, so that the spherical protrusion 2 at the lower part of the double ball rod 64 blocks the upper inner part of the connecting hard tube 53 and the lower inner part of the oxygen bag 52, and the upper part of the oxygen bag 52 is connected to the moving rod 3. First, the lid 2 is opened manually, so that the moving rod 3, the air bag frame 51, the oxygen bag 52, the connecting hard tube 53 and the air stone 54 are taken out of the culture tank 1 along with the lid 2. Then, the edible fungus liquid strain to be cultured is poured into the culture tank 1, and then the lid 2 is manually re-attached to the top of the culture tank 1, so that the moving rod 3, the air bag frame 51, the oxygen bag 52, the connecting hard tube 53, air stone 54, magnetic ring 61, two limit plates 62, magnetic ring 63, double ball rod 64, mounting frame 71, two hooks 73 and the lower parts of two reset rods 76 are all located in the lower part of the culture tank 1. Then, a certain amount of oxygen is manually introduced into the oxygen supply tube 4 at regular intervals. The oxygen supply tube 4 is connected with the interior of the moving rod 3, and the interior of the moving rod 3 is connected with the oxygen airbag 52, so that the oxygen in the oxygen supply tube 4 is passed into the oxygen airbag 52 along the moving rod 3, thereby causing the oxygen airbag 52 to begin to expand. At this time, the oxygen airbag 52 will begin to move upward under the action of buoyancy, and the oxygen airbag 52 will drive the moving rod 3, the airbag frame 51, the connecting hard tube 53, air stone 54, magnetic ring 61, two limit plates 62, magnetic ring 63, double ball rod 64, mounting frame 71 and two hooks 73 to move upward, and the limit plate 62 is separated from the lower part of the reset rod 76.

[0033] Then the oxygen bag 52 continues to move upward, and the two hooks 73 will contact the inclined surfaces 2 of the two squeezing blocks 75 respectively. At this time, the oxygen supply to the oxygen supply tube 4 is manually stopped, and the oxygen bag 52 will expand until it contacts both sides of the air bag frame 51. The inclined surfaces 2 of the squeezing blocks 75 will squeeze the hooks 73, causing the two hooks 73 to swing away from each other. The four torsion springs 74 are tightened, and the hooks 73 are disengaged from the limit plate 62. The hooks 73 no longer press against the limit plate 62, and the two reset springs 72 will reset, driving the two The limiting plate 62 and the magnetic ring 61 move downward. Since the magnetic properties of the magnetic ring 61 and the magnetic circle 63 are opposite, the magnetic ring 61 will attract the magnetic circle 63 and drive the magnetic circle 63 to move downward. The magnetic circle 63 drives the double ball rod 64 to move downward. The spherical protrusion on the upper part of the double ball rod 64 will contact the lower part of the inner part of the moving rod 3 and the upper part of the inner part of the oxygen bag 52. The spherical protrusion on the upper part of the double ball rod 64 will block the connection between the lower part of the inner part of the moving rod 3 and the upper part of the inner part of the oxygen bag 52, so that oxygen can no longer flow into the oxygen bag 52. , the spherical protrusion 2 at the lower part of the double ball rod 64 is separated from the lower part of the oxygen bag 52 and the upper part of the connecting hard tube 53. The oxygen in the oxygen bag 52 will enter the air stone 54 along the connecting hard tube 53 and then be discharged from the several air ports on the air stone 54. At this time, the oxygen bag 52 will gradually shrink and separate from the two sides of the air bag frame 51. As the amount of oxygen inside the oxygen bag 52 decreases, the oxygen bag 52 no longer has sufficient buoyancy, causing the oxygen bag 52, the moving rod 3, the air bag frame 51, the connecting hard tube 53, The air stone 54, the magnetic ring 61, the two limit plates 62, the magnetic ring 63, the double ball rod 64, the mounting bracket 71 and the two hooks 73 will move downward under the action of gravity. The oxygen in the oxygen bag 52 will gradually decrease during the downward movement until the oxygen bag 52 is in a deflated state again. The two hooks 73 will respectively disengage from the second inclined surfaces of the two extrusion blocks 75. The second inclined surfaces of the extrusion blocks 75 will no longer squeeze the hooks 73. The four torsion springs 74 will reset and drive the two hooks 73 to swing towards each other.

[0034] When the locking cam 73 is in the unlocked position, the locking cam 73 is in the unlocked position, and the locking cam 73 is in the unlocked position, so that the two locking cams 73 can no longer be unlocked, and the two can be unlocked when the master latch 7 is unlocked. 74 will reset and drive the two hooks 73 to swing towards each other, and the hook 73 will contact the limit plate 62 again. When the reset rod 76 presses against the limit plate 62, the limit plate 62, the magnetic ring 61, the magnetic ring 63 and the double ball rod 64 remain stationary, and the moving rod 3 continues to move downward and causes the airbag frame 51, the oxygen bag 52 and the connecting hard tube 53 to continue to move downward. The spherical protrusion 1 on the upper part of the double ball rod 64 is separated from the inner lower part of the moving rod 3 and the inner upper part of the oxygen bag 52, and the spherical protrusion 2 on the lower part of the double ball rod 64 contacts the inner lower part of the oxygen bag 52 and the inner upper part of the connecting hard tube 53. The spherical protrusion 2 on the lower part of the double ball rod 64 blocks the connection between the inner lower part of the oxygen bag 52 and the inner upper part of the connecting hard tube 53 again.

[0035] After that, a certain amount of oxygen is manually introduced into the oxygen supply tube 4, and the oxygen enters the oxygen bag 52 again along the moving rod 3, and the oxygen bag 52 is reciprocated. The buoyancy of the oxygen bag 52 during the oxygen filling process drives the air stone 54 to move upward. After the oxygen bag 52 is filled with enough oxygen, the extrusion block 75 squeezes the hook 73 and drives the two hooks 73 to swing, so that the limit plate 62 moves downward, and then drives the double ball rod 64 to move downward. The spherical protrusions at the upper and lower ends of the double ball rod 64 will block the upper part and the lower part of the oxygen bag 52 in turn, so that the oxygen in the oxygen bag 52 is discharged along the several air ports of the air stone 54. When the oxygen in the oxygen bag 52 decreases, the air stone 54 will move downward, so that the oxygen discharged by the air stone 54 can fully contact the edible fungus liquid strain in the culture tank 1. In this way, the air stone 54 moves upward as the oxygen content in the oxygen bag 52 increases, and the air stone 54 moves downward as the oxygen content in the oxygen bag 52 decreases, so that the oxygen stored in the oxygen bag 52 can be passed into the culture tank 1 from top to bottom, thereby more fully supplying oxygen to the edible fungus liquid strain in the culture tank 1, making the oxygen absorbed by the edible fungus liquid strain in the culture tank 1 more balanced, and making the fermentation of the edible fungus liquid strain more uniform and more complete.

[0036] Example 2: Based on Example 1, Figure 8 and Figure 9As shown, it also includes a stirring mechanism, which is arranged at the lower part of the moving rod 3. The stirring mechanism includes a rotating column 81, a column gear 82, a toothless rack 83 and a stirring plate 84. The lower part of the moving rod 3 is rotatably connected to the rotating column 81, and the rotating column 81 is arranged horizontally. The side of the rotating column 81 away from the moving rod 3 is connected to the column gear 82 through a flat key. The two reset rods 76 are welded with toothless racks 83 on the sides close to each other. Several tooth blocks are evenly spaced on the two toothless racks 83. The tooth blocks on the two toothless racks 83 are staggered. The two toothless racks 83 will engage with the column gear 82. Two stirring plates 84 are connected to the rotating column 81 by rivets, and the two stirring plates 84 are symmetrically arranged.

[0037] When the moving rod 3 moves upward, the moving rod 3 drives the rotating column 81, the two stirring plates 84 and the column gear 82 to move upward, and the column gear 82 will mesh with the two toothless racks 83 in turn. The two toothless racks 83 drive the column gear 82 to rotate back and forth at a certain angle, and the column gear 82 drives the rotating column 81 to rotate back and forth at a certain angle. The rotating column 81 drives the two stirring plates 84 to swing back and forth at a certain angle. When the moving rod 3 moves downward, the moving rod 3 drives the rotating column 81, the two stirring plates 84 and the column gear 82 to move downward. The toothless rack 83 drives the column gear 82 to continue to rotate back and forth at a certain angle, the column gear 82 drives the rotating column 81 to continue to rotate back and forth at a certain angle, the rotating column 81 drives the two stirring plates 84 to continue to swing back and forth at a certain angle, and the two stirring plates 84 will stir the edible fungus liquid strain in the culture tank 1. In this way, the edible fungus liquid strain in the culture tank 1 can be stirred, so that the oxygen discharged by the air stone 54 can contact the edible fungus liquid strain in the culture tank 1 more fully, thereby allowing the edible fungus liquid strain in the culture tank 1 to ferment more quickly.

[0038] Example 3: Based on Example 2, Figure 10 As shown, an airbag extrusion mechanism is also included, which is arranged on the airbag frame 51. The airbag extrusion mechanism includes a connecting block 91, an extrusion frame 92, a pressure spring 93 and a locking rod 94. Connecting blocks 91 are welded on both sides of the airbag frame 51, and the two connecting blocks 91 are symmetrically arranged. The two connecting blocks 91 are slidably connected to the extrusion frame 92 on the side close to each other. The two extrusion frames 92 are provided with an arc plate on the side close to each other. The arc plates of the two extrusion frames 92 are in contact with the oxygen airbag 52. A pressure spring 93 is connected between the extrusion frame 92 and the connecting block 91 by a hook. The lower parts of the two limit plates 62 are connected to the locking rod 94 by rivets, and the locking rod 94 will contact the arc plate of the extrusion frame 92.

[0039] When the oxygen in the oxygen supply tube 4 flows into the oxygen bag 52, the oxygen bag 52 will expand, and the oxygen bag 52 will contact the curved plates of the two extrusion frames 92. The oxygen bag 52 will squeeze the curved plates of the two extrusion frames 92, causing the two extrusion frames 92 to move away from each other. The two pressure springs 93 are compressed. When the hook 73 contacts the extrusion block 75, the two limit plates 62 will move downward and respectively drive the two locking rods 94 to move downward. The locking rods 94 contact the curved plates of the extrusion frames 92, and the locking rods 94 will contact the curved plates of the extrusion frames 92. The positioning rod 94 will press against the arc plate of the extrusion frame 92, and then the moving rod 3 moves downward, and the moving rod 3 drives the two positioning rods 94, the two extrusion frames 92 and the two connecting blocks 91 to move downward. At this time, the oxygen in the oxygen bag 52 gradually decreases, and the oxygen bag 52 is separated from the arc plates of the two extrusion frames 92. Then the limiting plate 62 contacts the reset rod 76, and the reset rod 76 presses against the limiting plate 62. The two limiting plates 62 and the two positioning rods 94 remain stationary, and the extrusion frame 92 continues to move downward. The positioning rod 94 When the cylinder 92 is in a state of being moved upward, the two cylinders 92 are in a state of being moved upward, and the cylinder 92 is in a state of being moved upward, so that the cylinder 92 is in a state of being moved upward, and the cylinder 92 is in a state of being moved upward, so that the cylinder 92 is in a state of being moved upward, and the cylinder 92 is in a state of being moved upward, so that the cylinder 92 is in a state of being moved upward, and the cylinder 92 is in a state of being moved upward, so that the cylinder 92 is in a state of being moved upward, and the cylinder 92 is in a state of being moved upward, so that the cylinder 92 is in a state of being moved upward, and the cylinder 92 is in a state of being moved upward, so that the cylinder 92 is in a state of being moved upward,

[0040] Example 4: Based on Example 3, Figure 10 As shown, it also includes an adjusting frame 10 and a knob 11. The upper part of the air stone 54 is rotatably connected to the adjusting frame 10. The lower part of the adjusting frame 10 is provided with four long plates. The four long plates of the adjusting frame 10 will contact several air ports on the air stone 54 in turn. The upper part of the adjusting frame 10 is welded with a knob 11, and the knob 11 is rotatably connected to the lower part of the connecting hard pipe 53.

[0041] First, different types of liquid bacteria have different oxygen requirements. The knob 11 is manually turned according to the oxygen requirement of the poured liquid bacteria. The knob 11 drives the adjustment frame 10 to rotate, so that the four long plates at the bottom of the adjustment frame 10 contact the several air ports on the air stone 54 in turn. The four long plates at the bottom of the adjustment frame 10 will block the several air ports on the air stone 54 in turn, and then the knob 11 is manually continued to be turned until the four long plates at the bottom of the adjustment frame 10 are adjusted to a suitable position, so that the amount of oxygen discharged from the several air ports on the air stone 54 can meet the oxygen requirement of the poured liquid bacteria. This makes it easy for humans to adjust the amount of oxygen discharged from the several air ports on the air stone 54 according to the oxygen requirement of the poured liquid bacteria, which is suitable for supplying oxygen to different types of liquid bacteria.

[0042] Example 5: Based on Example 4, Figure 6 As shown, a sealing ring 12 is also included. The sealing ring 12 is arranged inside the cover 2.

[0043] When oxygen is manually introduced into the oxygen supply pipe 4, the sealing ring 12 can seal the interior of the culture tank 1, preventing external bacteria from entering the interior of the culture tank 1 as much as possible, so that the edible fungus liquid strain in the culture tank 1 can ferment without external interference. At the same time, it also avoids the leakage of oxygen in the culture tank 1 as much as possible, which is more conducive to the cultivation of edible fungus liquid strains.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
